SPACs are, in practice, a Hail Mary for companies with little hope of ever going public the traditional way because they’re just not that attractive to real investors. Therefore, if a company goes public via a SPAC, you should assume they’re in a very weak position. So, while you could conceivably sue (and perhaps get a settlement out of them) it’s going to be a pretty poor outcome for you even in the best case scenario.
If you look at buzzfeed for example (if I had to guess, that’s the company you’re with) they’re basically circling the drain and the SPAC was a last ditch effort: if the burned employees of buzzfeed sue them, where’s the money going to come from? Buzzfeed can barely keep the lights on.
If they’re offering to work on contingency, go for it, nothing to lose, but don’t pin your hopes on seeing anything close to your unrealised gains.
